Abstract
In this research article, aluminium alloy plates of 6mm thickness AA5052 and AA6061 are to be joined by using friction stir welding (FSW). Present study aims at investigating the influence of the process parameters on the mechanical properties such as tensile strength and hardness of the dissimilar metal adding of copper powder. Using design of experiments Taguchi’s experimental L9 layout was used to carry out the experiments with addition of copper powder. Threaded pin tool geometry was used for conducting the experiments. Based on the results and Taguchi analysis it was found that 900 rpm and welding speed of, 40 mm/min, 4KN, 20 degree was found for the maximum tensile strength (162.233N/mm2), with addition of copper powder. 1000 rpm and welding speed of, 45 mm/min, 4KN, 10 degree was found for the maximum hardness (18 HRA), with addition of copper powder
